write a note conservation of bio diversity and conservation of natural resource
Answers
Biodiversity is the biological diversity which includes the variety of the whole species present on earth. It includes different animals, plants, micro-organisms and their genes, water ecosystems, terrestrial, and marine ecosystems in which they all are present.
Biodiversity is necessary for our existence as well as valuable in its own right. This is because it provides the fundamental building blocks for the many goods and services which provides a healthy environment to lead our life.
Biodiversity include fundamental things to our health like fresh water clean air and food products, as well as the many other products such as timber and fiber.
Biodiversity also includes various other important things and services such as cultural, recreational, and spiritual nourishment that play an important role in maintaining our personal life as well as social life.
So, it is an important task for all of us to take care of our Biodiversity and we should try to maintain it. Over the last 200 years Australia has suffered the largest ocumented decline in biodiversity of any continent. Despite efforts to manage threats and pressures to biodiversity in Australia, it is still in decline.
Main threats to our biodiversity are as given below:
• Degradation, fragmentation and loss of habitat
• Spreading of invasive species
• Unsustainable use of natural resources
• Change of Climate
• Inappropriate fire regimes
• Changes within aquatic environment and water flows
Why should we Conserve Biodiversity?
Human should conserve biodiversity because of its benefit for example services and biological resources which are essential to live our life on earth. However, it also provides spiritual benefits as well as social benefit.
Conservation of Bio-Diversity and Natural Resources
Aldo Leopold wisely remarks, “Conservation is a state of harmony between man and environment." Conservation is not an option; it is the only direst necessity. Without it, man may jeopardize his own survival. Our natural resources are not only precious, they are invaluable! Man has been so much engrossed in his progress and prosperity; he does not have time to see the irreparable damage that he is doing to the health of planet earth.
The present rate at which the natural resources are being used is quite alarming. The rate of consumption is faster than the rate of their natural replenishment. If the rate of consumption is not reduced, soon all the natural resources will be used up. There won't be left anything for the coming generations. Now the question arises; "Are we to leave a scorched planet to the coming generations?" We will be called highly selfish generation, if we don't leave any natural resources for the future generations. We need to put our acts together. We must follow the principles of sustainable development. We must allow nature to replenish its resources.
Forests are the lungs of our planet earth, without forests our earth will be as barren as hell. Most of the world oxygen that the animal species including man inhale is produced in the tropical rainforests. More than half of the world's estimated 10 million species of plants, animals and insects live in the tropical rainforests. They are important to the environment as they recycle water and regulate levels of carbon dioxide in the atmosphere through photosynthesis. They are the world's full-time regulators of air and water. Their cutting will disturb the natural water cycles which will lead to the shortage of fresh-water in the water reserves of the world. The abundant bio-diversity and natural resources given to us by God are indispensable parts of the big WHOLE called life. We must maintain them for life to go on.
The tropical rainforests are also very important because they are home to an enormous number of plants and animals. Even more importantly, they are home to many unique plants and animals that do not exist anywhere else in the world. If the tropical rainforests were to be destroyed, so would the homes of all these species. Without a home, many of these species could become extinct.
Let's cooperate with nature to allow us to continue living in abundance. Let's not be selfish and avaricious. After all it is our responsibility to bequeath a healthy and prosperous planet. Being parents it is our moral responsibility. Let's take care of our planet and use the natural resources wisely and frugally! Man cannot create like God; however, man can conserve what he has received from God.
